SampleValue * JpegSampleValue::getNearestTargetSampleValue

(

EmbValue

t

)

const [virtual]

get the nearest (with the least distance to this sample value) sample value whose embedded value equals the specified target

Parameters:

t

the target embedded value

If two or more target sample values have equal distance each of them should be returned with equal probability.

The returned SampleValue object should be deleted by the callser.

Implements SampleValue.

UWORD32 JpegSampleValue::calcDistance

(

const SampleValue *

s

)

const [virtual]

calculate the distance between the sample value s and this sample value

Parameters:

s

a sample value of the same type as this

Returns:

the distance

Implements SampleValue.

std::string JpegSampleValue::getName

(

void

)

const [virtual]

return a short name uniquely identifying this sample value
